A solid in which electrons are able to move easily from one atom to another is called a conductor. Conductors allow electric current to flow freely through them due to the mobility of electrons. Metals like copper and aluminum are examples of good conductors.
Charge is usually transferred by electrons because electrons are the negatively charged particles within an atom that are easily able to move from one atom to another, allowing for the transfer of electrical charge.

In metals, electricity flows through the movement of free electrons from atom to atom. These electrons can move easily through the material, creating an electric current.
Electrons
conductors conduct electricity well because the electrons are easily transfered from atom to atom.
The material that allows electrons to freely pass from one atom to another is called a conductor. Conductors have loosely bound electrons that are able to move easily through the material in response to an electric field. Metals are examples of good conductors due to their abundance of free electrons.
An oxygen atom is able to attract 2 additional electrons to complete its valence shell and achieve a stable octet configuration. This is because oxygen has 6 valence electrons and needs a total of 8 electrons for stability.
The number of electrons an atom has in its outer shell, and how easily those electrons can be gained or lost, determines an atom's reactivity. Electrons play a crucial role in forming chemical bonds, and the availability of electrons in the outer shell influences how likely an atom is to react with other atoms.
